Dr. Antonio Machado (Madrid, 1953) has been a lecturer in Ecology at the University of La Laguna (Tenerife, Canary islands), superintendent of Teide National Park, adviser on environmental policies for the Presidency of the Spanish Government, regional councillor of the IUCN (International Union for Conservation of Nature) and president of the (European Centre for Nature Conservation (ECNC). He has also worked as independent consultant for several international organizations and foreign co-operation programmes. He retired in July 2018 when heading a public foundation in the Canary Islands (Granadilla Environmental Observatory) and now he continues to research privately in Entomology (started in 1975). He is also editor-in-chief of the Journal for Nature Conservation (Elsevier group) and is a full member of the World Academy of Arts and Science and of the Canarian Academy of Language.

It can easily be distinguished by less sculptured elytra, its differently shaped antennal scrobe, and by the pronotum not constricted anteriorly and expanded over the head. Some ecological data are also provided, and considerations on the fauna occurring in the mesovoid shallow substratum (MSS) from the locality of this new species are made. Additional records and comments on other Oromia species as well as an identification key to the species of the genus are given.

Dapsa curta Franz, 1976 is also poorly described and based on a single female. Without a male it is not possible to assess with full confidence if it belongs to the African genus Danae or more probably to the Oriental genus Tragoscelis, and to which species. It is for sure not a Dapsa and its Canarian origin relates probably to another labeling error of the author, who also collected in Borneo, where this latter genus is present with 5 species. Consequently, Dapsa curta Franz, 1996 is proposed as nomen dubium.

W hy are there so many Laparocerus? The swarm of 261 species and subspecies in Madeira, Salvages ... more W hy are there so many Laparocerus? The swarm of 261 species and subspecies in Madeira, Salvages and the Canary Islands is the result of a blend of adaptive and non-adaptive evolution in old volcanic archipelagos. These have plenty of environmentally dissected islands subject to a dynamics of construction and deconstruction. A twenty year-long prospection and a DNA phylogenetic analysis reveal their monophyly, internal relationships, and plausible pathways of colonisation, which started in the late Miocene. Within a timeframe of about 9 million years, sequential radiation events have generated several monophyletic groups, 25 in total, that have been recognised as subgenera of Laparocerus. Colonisation routes, habitat shifts, disruption of populations by volcanism, dispersal by massive landslides, and other important factors for speciation are discussed in depth. Laparocerus weevils are all flightless and most taxa are exclusive to one single island-seventeen in totalhaving occupied almost all habitats, from the coastal shrublands to the sclerophyllous woodlands, evergreen cloud-forest, pine woodlands, high-mountain shrublands and the underground environment (volcanic lava-tubes). They thus show an extraordinary morphological and ecological plasticity. Only two species inhabit NW Africa, the nearest continental land, but as a result of a back-colonisation. The richest island is Tenerife (2034 km 2) with 68 species and subspecies. Overall, there is an outstanding ratio of one endemic Laparocerus per 31 km 2 , a record not beaten by any other plant or animal genus in Macaronesia. If oceanic islands have been traditionally considered as laboratories of evolution and species-producing machines, Laparocerus will become an ideal model species for broadening research into dispersal and speciation processes of all kinds. Such a group provides a fine-grain picture of nature and evolution at work. To assist in this endeavour, this book authored by A. Machado provides a full revision of the genus Laparocerus, with descriptions of all 264 species and subspecies-doubling the number previously known-keys for their identification, 374 macro-photographs of the imagos, 50 plates with line-drawings of their genitalia and other internal pieces, and 47 distribution maps. It also incorporates a detailed anatomical study (13 plates) of one species including preimaginal stages, and chapters dealing with their breeding biology, ecology (food-plants, habitats, etc.), and behaviour. Their natural history, in other words. The author hopes that in the near future Laparocerus will merit sharing the podium with Darwin's finches or Drosophila in studies of island evolution. The Macaronesian LAPAROCERUS Champions of biodiversity. A weevil genus beats records of explosive evolutive radiation on oceanic islands in Macaronesia
